What does the Peek function return?

The Peek function in Qlik Sense is designed to retrieve a specific value from a field based on its position in a dataset. It allows you to specify both the row number and the field from which you want to obtain the value. This is particularly useful when you need to access data from a specific row in a table while performing data transformations or manipulations within your script.

By using the Peek function, you can retrieve values dynamically based on your requirements, making it a powerful tool for data scripting in Qlik Sense. This flexibility provides the ability to handle data analysis tasks effectively, such as checking previous values, performing calculations based on specific records, or creating complex data flows that rely on the value at a certain position in your dataset.

In contrast, the other options describe behaviors that the Peek function does not perform. For instance, accessing the first or last records refers to more general data extraction mechanisms, which do not leverage the specific row-based retrieval capability of the Peek function. Similarly, obtaining the total count of records pertains to aggregate functions rather than retrieving individual field values. Therefore, the correct understanding of the Peek function aligns with its ability to return a specific field value based on a defined row and table specification.
